GEM-SETTING.

SPECIFICATION forming part of Letters Patent No, 384,399, dated June 11889- (No model.)

To aZZ whom it may concern.-

Be it known that I, \VARREN G. SMITH, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented a new and useful Improvement in Gem-Setting, of which thefollowing is a specification.

Myinvention relates to gem-setting, as here ina-fter fully described,illustrated in the drawings, and specifically pointed out in the claims.

Referring to the accompanying drawings, wherein like letters ofreference point out similar parts on each figure, Figure 1 is aperspectiveview ofashirt-stnd, the jewel of which is mounted inaccordance with my invention. Fig. 2 is an enlarged view of an ear-ringwithout any setting, showing one pair of prongs with their extensionspartially separated. Fig. 3 represents detail views of the invention anattached to any base, some prongs being disunited.

In the drawings, A represents the metal mounting, which consists of acurved base, a, from which extend upwardly aseries of prongs, 1 1 havingupper extensions. 2, which in practice are upset over marginal facets ofthe gem, as plainly shown in Fig. 1. The prongs 1 1 rise upwardly incouples from an invertedly-curvcd base, (I, thus forming a series ofU-shaped members, one arm of each U composing a prong, l, and .theopposite one a prong, 1. (See detail, Fig. 3.) 5 is a ring orfilletcommon in gem-settings. In practice the adjacent side edges ofindependent couples of said prongs are respectively joined in alignment,commencing a short distance from above the curved base, leaving towardthe lower ends of each couple of jointed prongs a series of openings, 4,nearly triangular in shape. I thus provide an exceedingly graceful andserviceable setting, securing great strength with employment ofa minimumquantity and weight of metal. Besides this advantage the openingsl,surrounding the lower part of the mounting, serve the purpose ofadmitting light therethrough, reflecting and refract ing light to andfrom the lower facets of the gem, a very desirable result, especially inimitation gems, increasing their translucency and brilliancy.

The upper turned-over extensions, 2, which are the terminal points ofthe prongs, are in practice closely united in couples, and their uppersurfaces are finished to a plane by filing, polishing, bnrnishing, orany means well known to all familiar in the art to which my invention isallied.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. An improved jewel-setting composed of a series of independent prongsspringing from an invertedly-curved base and joined together in couplesat their side edges in right lines from a short distance above said baseto their terminal points, substantially as described.

2. An improved jewel-setting consisting of aseries of independentU-shaped members, adapted and arranged to surround the sides of a gem,the vertical arms 1 l of each of the series being alternately joinedfrom their terminal points in alignment down to near their curved basea, in combination with openings 4 at the lower end of each couple ofprongs, substantially as described.

3. An improved jewel-setting consisting of ascries of independent pairsof prongs extending upwardly from an invertedly-arched base, eachuprising prong being connected lengthwise to the next adjoining prong,said bases attached to and in combination with a lower ring, 5,substantially as described.
